[TIMOB-18417] Windows: Generate an overview of Windows API implementation coverage

It'd be nice to have some HTML page generated that gives a quick overview of how far we are in terms of implementing proxies. It's painful to gather that sort of info by looking through the doc pages. We're already generating YML files and merging it into the JSCA. A single webpage with a rundown of all the classes, properties, methods (and events?) and a simple green/red status would be pretty helpful to quickly glance through and get a high level overview of how far we are.
